Description
Technical Field
[0001] This utility model relates to the field of fire-resistant busbar technology, specifically a fire-resistant busbar that can be quickly connected. Background Technology
[0002] With the emergence of modern engineering facilities and equipment, electricity consumption in all industries has increased rapidly. In particular, with the emergence of numerous high-rise buildings and large factory workshops, traditional cables, as power transmission conductors, can no longer meet the requirements of high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction. Busbar trunking, as a new type of power distribution conductor, has emerged. It is a closed metal device composed of copper and aluminum busbar columns, used to distribute a large amount of power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.
[0003] When using existing busbar trunking, multiple busbar trunkings need to be connected due to environmental or operational requirements. During splicing, the metal conductor connecting pieces between the busbar trunkings must first be butted together, then the metal conductor connecting pieces are fixed with bolts, and finally the busbar trunking protective cover is butted together with multiple bolts. Therefore, when splicing the busbar trunking protective cover, the workers need to tighten the bolts multiple times, making the installation quite troublesome and greatly reducing the convenience of connecting the busbar trunking.
[0004] Chinese Utility Model Patent Publication Number: CN 222423152 U discloses a quick-connect fire-resistant busbar trunking. This quick-connect fire-resistant busbar trunking, through the cooperation of a pull button, a limit rod, and a tension spring, allows for easy initial connection of two sets of busbar trunking. Through the cooperation of a knob and a first lead screw, two sets of plug-in seats can easily drive two sets of plug rods into the inner side of the limit hole, locking the plug-in blocks in place. Through the cooperation of a drive wheel, a belt, and a driven wheel, two sets of plug-in seats on the outer side of the second lead screw can drive the plug rods into the inner side of the limit hole, achieving quick connection of two sets of busbar trunking. However, this quick-connect fire-resistant busbar trunking relies on the synchronous movement of multiple components such as the lead screw, belt, and drive wheel during connection. Long-term use may lead to problems such as belt slippage and lead screw thread wear, causing the upper and lower plug rods to be out of sync, affecting connection reliability. Furthermore, it lacks a detachable structure, and the internal transmission structure (such as the pulley set) requires regular lubrication and tension adjustment, making maintenance inconvenient in the enclosed environment of the fire-resistant busbar trunking. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to provide a fire-resistant busbar trunking that can be quickly connected, which can effectively solve the problems in the prior art.
[0006] The technical solution adopted by this utility model is: a fire-resistant busbar trunking that can be quickly connected, including a busbar trunking body, locking components are fixedly installed on both sides of the busbar trunking body, a first mounting component is provided at one end of the busbar trunking body, and a second mounting component is provided at the other end of the busbar trunking body. The first and second mounting components and the locking components are all plug-in installed. A connecting component is provided between the first and second mounting components. A locking screw is provided on the outside of the connecting component. Grooves are provided at both ends of the busbar trunking body near the first and second mounting components.
[0007] The locking assembly includes a fixing seat, and a slot for positioning the first mounting component and the second mounting component is provided at one end of the fixing seat near the first mounting component. A support seat is fixedly installed at the other end of the fixing seat away from the busbar trunking body. A locking block for fixing the first mounting component and the second mounting component is provided between the support seat and the fixing seat.
[0008] The first installation component includes a connecting plate, an expansion sealing strip, and a connecting block. The first installation component has a connecting plate on the side near the busbar trunking body. The end of the connecting plate near the fixing seat is fixedly installed with a plug-in block that is plugged into the slot. The outer side of the plug-in block has a slot that engages with the locking block.
[0009] The second mounting assembly includes a second connecting plate, a second expansion sealing strip, and a mounting groove. The second mounting assembly has a second connecting plate on one side near the busbar trunking body. The end of the second connecting plate near the fixing seat is fixedly mounted with a second plug block that is plugged into the slot. The outer side of the second plug block has a second slot that engages with the second plug block.
[0010] Preferably, the locking assembly further includes a through hole, a support base, a return spring, a release buckle, a release groove, and a release pin.

A return spring is fixedly installed at the other end of the locking block away from the fixed base. A release buckle is provided on the outer side of the locking block. A release groove is provided at a fixed position on the top of the support base, and a release pin is provided on the side of the release groove away from the support base.
[0011] Through the above technical solution, by setting the locking component, the busbar trunking body can be quickly installed with the first installation component and the second installation component. By using the elastic action of the return spring, when the locking component is inserted into the first and second insertion blocks, the return spring is forced to move outward until the locking block is engaged in the first and second slots, thereby quickly locking the first and second installation components.
[0012] Preferably, the disconnect pin can be inserted into the disconnect groove, and the disconnect pin can be engaged in the disconnect buckle.
[0013] With the above technical solution, the disconnecting pin can be inserted into the disconnecting slot and the disconnecting buckle. When the staff needs to disassemble the first installation component and the second installation component, they only need to pull the disconnecting pin to move the disconnecting buckle outward, so that the locking block is disengaged from the locking slot one and the locking slot two. At this time, the first installation component and the second installation component can be disassembled on the side away from the busbar trunking body, which facilitates the detachable installation of the first installation component and the second installation component.
[0014] Preferably, the connecting component includes a connecting seat, a conductive block, a wire groove, a connecting groove, and a screw hole. The connecting component is inserted and installed with the first mounting component and the second mounting component through the connecting groove. The first mounting component and the second mounting component are provided with connecting seats. The connecting seat is provided with a conductive block inside. The inner side of the conductive block is provided with a wire groove corresponding to the busbar. The outer side of the connecting groove is provided with a screw hole.
[0015] With the above technical solution, by setting the inner wire groove of the conductive block to correspond with the busbar, when the workers connect the two sets of busbar groove bodies, they only need to insert the wire groove that is aligned with the busbar.
[0016] Preferably, the first installation component further includes an expansion sealing strip, a limiting hole, a connecting block, and a screw hole. An expansion sealing strip is provided at one end of the connecting plate near the busbar trunking body. Multiple limiting holes corresponding to the busbars are provided on the inner side of the connecting plate. Two sets of connecting blocks are fixedly installed at the end of the connecting plate away from the busbar trunking body. Screw holes for fixing to locking screws are provided on the outer side of the two sets of connecting blocks.
[0017] By using the above technical solution, and by setting the first installation component limiting hole one to correspond with the busbar, the busbars in the busbar trunking body are arranged in an orderly manner through the limiting hole one and inserted into the conductor groove during installation, which effectively improves the storage of the busbars.
[0018] Preferably, the second mounting component further includes an expansion sealing strip II, a limiting hole II, a mounting groove and a screw hole III. An expansion sealing strip II is provided at one end of the connecting plate II near the busbar trunking body. A plurality of limiting holes II corresponding to the busbar are opened on the inner side of the connecting plate II. An mounting groove is fixedly installed at one end of the connecting plate II away from the busbar trunking body. A screw hole II for fixing to the locking screw is provided on the outer side of the mounting groove.
[0019] The above technical solution includes a second mounting component, which can be easily connected to the connecting component by plugging and engaging with the first mounting component. The second mounting component can also be quickly disassembled from the first mounting component via the screw hole, facilitating maintenance work by staff in the future.
[0020] Preferably, the connecting block and the mounting slot are plug-in installed, and the width of the connecting block and the mounting slot is the same as the width of the connecting slot. The connecting component can be plugged into the first mounting component and the second mounting component through the connecting block and the mounting slot.
[0021] With the above technical solution, during installation, the first and second mounting components are quickly plugged into the outside of the busbar trunking body using plug one and plug two. Then, the connecting block and the mounting groove are positioned and installed, and the width of the connecting block and the mounting groove are the same as the width of the connecting groove. This allows the connecting component to be positioned and installed inside the first and second mounting components while connecting them. At this time, the wire groove inside the connecting block corresponds to the limiting hole one and the limiting hole two, which facilitates the power connection of the busbar. Then, the first and second mounting components and the connecting component can be quickly fixed by tightening the screws.
[0022] Preferably, the first and second expansion sealing strips can be inserted into the interior of the groove.
[0023] Through the above technical solution, the expansion sealing strips one and two at the joint expand and seal the gaps after high temperature expansion, which can effectively prevent the fire from spreading along the busbar when a fire occurs.
[0024] Compared with the prior art, this utility model provides a fire-resistant busbar trunking that can be quickly connected, which has the following advantages:
[0025] 1. This quick-connect fire-resistant busbar trunking allows for the rapid insertion and installation of the first and second mounting components into the slots via plug-in blocks one and two. The first and second mounting components are then quickly locked in place by engaging the locking blocks with slots one and two. When workers need to disassemble the first and second mounting components, they simply pull the disconnect pin to move the disconnect latch outwards, disengaging the locking blocks from slots one and two. The first and second mounting components can then be disassembled away from the busbar trunking body. This design enables the busbar trunking to have a quick-connect function, and the connected busbar trunking can be quickly disassembled, improving the assembly and disassembly speed and thus increasing the installation efficiency of workers.
[0026] 2. This quick-connect fire-resistant busbar trunking connects with the mounting slot via a connecting block. The width of the connecting block and the mounting slot is the same as the width of the connecting slot. This allows the connecting component to be positioned between the first and second mounting components while simultaneously connecting them. At this time, the wire groove inside the connecting block corresponds to the first and second limiting holes, facilitating the power connection of the busbar. Subsequently, the first and second mounting components can be quickly fixed to the connecting component by tightening the screws. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0038] Example 1: As Figure 1-9 As shown, the present invention provides a fire-resistant busbar trunking that can be quickly connected, including a busbar trunking body 1. Locking components 2 are fixedly installed on both sides of the busbar trunking body 1. A first mounting component 4 is provided at one end of the busbar trunking body 1, and a second mounting component 5 is provided at the other end of the busbar trunking body 1. The first mounting component 4 and the second mounting component 5 are all plug-in installed with the locking components 2. A connecting component 3 is provided between the first mounting component 4 and the second mounting component 5. A locking screw 6 is provided on the outside of the connecting component 3. Grooves 7 are provided at both ends of the busbar trunking body 1 near the first mounting component 4 and the second mounting component 5.
[0039] The locking component 2 includes a fixing base 201. The fixing base 201 has a slot 202 for positioning the first mounting component 4 and the second mounting component 5 at one end near the first mounting component 4. A support base 204 is fixedly installed at the other end of the fixing base 201 away from the busbar trunking body 1. A locking block 205 for fixing the first mounting component 4 and the second mounting component 5 is provided between the support base 204 and the fixing base 201.
[0040] The first mounting component 4 includes a connecting plate 401, an expansion sealing strip 402, and a connecting block 406. The first mounting component 4 is provided with a connecting plate 401 on the side near the busbar trunking body 1. A plug block 404 is fixedly installed on the end of the connecting plate 401 near the fixing seat 201, which is plugged into the slot 202. A slot 405 is provided on the outer side of the plug block 404 to engage with the locking block 205.
[0041] The second mounting component 5 includes a connecting plate 501, an expansion sealing strip 502, and a mounting groove 506. The connecting plate 501 is provided on the side of the second mounting component 5 near the busbar trunking body 1. A plug block 504 is fixedly installed on the end of the connecting plate 501 near the fixing seat 201, which is plugged into the slot 202. A slot 505 is provided on the outer side of the plug block 504 to engage with the locking block 205.
[0042] Specifically, the locking assembly 2 also includes a through hole 203, a support base 204, a return spring 206, a disconnect buckle 207, a disconnect groove 208, and a disconnect pin 209. The fixed base 201 has a through hole 203 at one end away from the busbar trunking body 1. The fixed base 201 has a support base 204 fixedly installed at one end away from the busbar trunking body 1. The locking block 205 has a return spring 206 fixedly installed at one end away from the fixed base 201. The locking block 205 has a disconnect buckle 207 on its outer side. The top fixed position of the support base 204 has a disconnect groove 208. The disconnect groove 208 has a disconnect pin 209 on the side away from the support base 204. The advantage is that by setting the locking component 2, the busbar trunking body 1 can be quickly installed with the first mounting component 4 and the second mounting component 5. Through the elastic action of the return spring 206, when the locking component 2 is inserted into the first plug 404 and the second plug 504, the return spring 206 is forced to move outward until the locking block 205 is engaged in the first slot 405 and the second slot 505, thereby achieving quick locking of the first mounting component 4 and the second mounting component 5.
[0043] Specifically, the disconnecting pin 209 can be inserted into the disconnecting slot 208, and the disconnecting pin 209 can be engaged in the disconnecting buckle 207. The advantage is that, because the disconnecting pin 209 can be inserted into the disconnecting slot 208 and the disconnecting buckle 207, when the operator needs to disassemble the first mounting component 4 and the second mounting component 5, they only need to pull the disconnecting pin 209 to move the disconnecting buckle 207 outwards, thereby causing the locking block 205 to disengage from the locking slot 1 405 and the locking slot 2 505. At this time, only the side of the first mounting component 4 and the second mounting component 5 away from the busbar trunking body 1 needs to be disassembled, facilitating the detachable installation of the first mounting component 4 and the second mounting component 5.
[0044] Specifically, the connecting component 3 includes a connecting seat 301, a conductive block 302, a wire groove 303, a connecting groove 304, and a screw hole 305. The connecting component 3 is inserted and installed with the first mounting component 4 and the second mounting component 5 through the connecting groove 304. The first mounting component 4 and the second mounting component 5 are provided with connecting seats 301. The conductive block 302 is provided inside the connecting seat 301. The inner side of the conductive block 302 is provided with a wire groove 303 corresponding to the busbar. The outer side of the connecting groove 304 is provided with a screw hole 305. The advantage is that by setting the wire groove 303 on the inner side of the conductive block 302 to correspond to the busbar, when the operator connects the two sets of busbar trunk bodies 1, they only need to insert the wire groove 303 that the busbar is aligned with.
[0045] Example 2: Figure 2-9 As shown, this is an improvement on the previous embodiment.
[0046] Specifically, the first installation component 4 also includes an expansion sealing strip 402, a limiting hole 403, a connecting block 406, and a screw hole 407. The connecting plate 401 has an expansion sealing strip 402 at its end near the busbar trunking body 1. Multiple limiting holes 403 corresponding to the busbars are provided on the inner side of the connecting plate 401. Two sets of connecting blocks 406 are fixedly installed at the end of the connecting plate 401 away from the busbar trunking body 1. Screw holes 407 for fixing to the locking screws 6 are provided on the outer side of the two sets of connecting blocks 406. The advantage is that by setting the limiting holes 403 of the first installation component 4 to correspond to the busbars, during installation, the busbars in the busbar trunking body 1 are arranged orderly through the limiting holes 403 and inserted into the conductor groove 303, effectively improving the storage capacity of the busbars.
[0047] Specifically, the second mounting component 5 also includes an expansion sealing strip 502, a limiting hole 503, a mounting groove 506, and a screw hole 507. The expansion sealing strip 502 is provided at one end of the connecting plate 501 near the busbar trunking body 1. Multiple limiting holes 503 corresponding to the busbars are provided on the inner side of the connecting plate 501. The mounting groove 506 is fixedly installed at the end of the connecting plate 501 away from the busbar trunking body 1. A screw hole 407 for fixing to the locking screw 6 is provided on the outer side of the mounting groove 506. The advantage is that the second mounting component 5, through its insertion and engagement with the first mounting component 4, facilitates quick connection between the first mounting component 4 and the second mounting component 5 and the connecting component 3. Furthermore, the screw hole 407 allows for quick disassembly of the first mounting component 4 and the second mounting component 5, facilitating subsequent maintenance work.
[0048] Specifically, the connecting block 406 and the mounting groove 506 are plug-in installed. The width of the connecting block 406 and the mounting groove 506 is the same as the width of the connecting groove 304. The connecting component 3 can be plugged into and installed with the first mounting component 4 and the second mounting component 5 through the connecting block 406 and the mounting groove 506. The advantage is that during installation, the first mounting component 4 and the second mounting component 5 are quickly plugged into and installed on the outside of the busbar trunking body 1 using plug 404 and plug 504. Then, the connecting block 406 is positioned and installed in the mounting groove 506. The width of the connecting block 406 and the mounting groove 506 is the same as the width of the connecting groove 304. This allows the connecting component 3 to be positioned and installed inside the first mounting component 4 and the second mounting component 5 while connecting the first mounting component 4 and the second mounting component 5. At this time, the wire groove 303 inside the connecting block 406 corresponds to the limiting hole 403 and the limiting hole 503, which facilitates the power connection of the busbar. Then, the first mounting component 4 and the second mounting component 5 can be quickly fixed to the connecting component 3 by tightening the screw 6.
[0049] Specifically, expansion sealing strip 402 and expansion sealing strip 502 can be inserted into the groove 7. The advantage is that the expansion sealing strip 402 and expansion sealing strip 502 at the joint, after expanding at high temperature, seal the gaps and effectively prevent the fire from spreading along the busbar in the event of a fire.
[0050] Working principle: In use, the first mounting component 4 and the second mounting component 5 are quickly inserted into the slot 202 using the first insertion block 404 and the second insertion block 504. Then, the first mounting component 4 and the second mounting component 5 are quickly locked by the engagement of the locking block 205 with the first and second slots 405 and 505. When the operator needs to disassemble the first mounting component 4 and the second mounting component 5, simply pull the disconnecting pin 209 to move the disconnecting buckle 207 outwards, thereby disengaging the locking block 205 from the first and second slots 405 and 505. At this point, the first mounting component 4 and the second mounting component 5 can be disassembled away from the busbar trunking body 1. Finally, they are connected by the cooperation of the connecting block 406 and the mounting groove 506, and the width of the connecting block 406 and the mounting groove 506 is the same as the width of the connecting groove 304. With the same degree of precision, when connecting the first mounting component 4 and the second mounting component 5, the connecting component 3 can be positioned and installed inside the first mounting component 4 and the second mounting component 5. At this time, the wire groove 303 inside the connecting block 406 corresponds to the limiting hole 1 403 and the limiting hole 2 503, which facilitates the power connection of the busbar. Then, the first mounting component 4 and the second mounting component 5 can be quickly fixed to the connecting component 3 by tightening the screw 6. This realizes that the busbar trunking has a quick docking function, and the docked busbar trunking can also be quickly disassembled, which improves the disassembly and assembly speed of the busbar trunking, thereby improving the installation efficiency of the workers. Furthermore, by expanding the sealing strip 1 402 and the sealing strip 2 502 at the joint, the gaps are sealed after high temperature expansion, which can effectively prevent the fire from spreading along the busbar when a fire occurs, thus improving the fireproof effect of the device.
[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
